Description
<Desc/Clms Page number 1>
Die Erfindung betrifft ein vertikalachsiges, durch eine Windfahne zur Windrichtung ausrichtbares Windrad, welches um parallel zur Radachse liegende Achsen schwenkbare Strömungsprofile aufweist, die kreisförmig um die Achse des Windrades angeordnet sind, wobei die Strömungsprofile über einen Exzenterantrieb bezüglich der Windrichtung jeweils in den günstigsten Anstellwinkel einstellbar sind. Bei dieser bekannten Ausbildung weist das Windrad schwenkbare, einteilige und damit in sich starre Strömungsprofile auf, die insbesondere bei ihrer Schrägstellung zur Windrichtung Luftwirbel erzeugen, welche einen Leistungsverlust des Windrades verursachen.
Dieser Nachteil wird erfindungsgemäss dadurch vermieden, dass die Strömungsprofile aus zwei in Strömungsrichtung hintereinanderliegenden Teilen bestehen, deren vordere Teile stets parallel zur Windrichtung ausgerichtet sind und deren hintere Teile über den Umlaufweg des Windrades, in Windrichtung gesehen, im vorderen und hinteren Bereich im Sinne eines gleichgerichteten Drehantriebes durch den Exzenterantrieb auslenkbar sind.
In den Zeichnungen ist ein Ausführungsbeispiel der Erfindung dargestellt. Fig. l zeigt einen Vertikalschnitt durch die Windkraftmaschine nach der Linie I-I in der Fig. 2. Fig. 2 stellt die Draufsicht auf die Windkraftmaschine in einer Ausführung mit vier Strömungsprofilen in Ruhestellung dar. In Fig. 3 ist eine Windkraftmaschine mit acht Strömungsprofilen in Arbeitsstellung dargestellt, wobei im wesentlichen nur die Verstellung durch Exzenter und Exzentergabel hervorgehoben wird.
Fig. 4 zeigt die Strömungsprofilstellungen über den Umlaufweg des Windrades, wobei deren vordere Teile der aus zwei in Strömungsrichtung hintereinanderliegenden Teilen bestehenden Strömungsprofile stets parallel zur Windrichtung ausgerichtet sind und deren hintere Teile über den Umlaufweg des Windrades, in Windrichtung gesehen im vorderen und hinteren Bereich im Sinne eines gleichgerichteten Drehantriebes durch den Exzenterantrieb auslenkbar sind.
Mit der Zentralachse-l-fest verbunden ist eine obere --2-- und eine untere --3-- Lagerscheibe. In der oberen Lagerscheibe --2-- befinden sich Strömungsprofilwellenlager-18-und in der unteren Lagerscheibe --3-- Lagerzapfen --19--. Im inneren oberen Ende der Zentralachse - ist eine Steuerwelle --5-- mittels Kugellager --20-- gelagert. Die in einen Kurbelzapfen auslaufende Steuerwelle --5-- dient der Lagerung der Steuerscheibe --4-- und ist mit einer Wind-
EMI1.1
für einen Lenkhebel --7-- zugeordnet. Der Lenkhebel --7-- ist mit einer Profilwelle --8-- fest verbunden. Die Profilwelle --8-- ist mittels der Lager --18-- in der oberen Lagerscheibe --2-und in der unteren Lagerscheibe --3-- auf einem Lagerzapfen --19-- gelagert.
Um die Bewegung einer Wellengabel --13-- zu ermöglichen, ist die Profilwelle --8-- vor dem Zapfenlager --18-gekröpft. Jedes Strömungsprofil besteht aus einem mit der Profilwelle --8-- fest verbundenen Vorderteil --9-- und einem in den Lagern --23-- mittels Welle --10-- gelagerten Hinterteil --11--.
Jede Welle --10-- ist am unteren Ende mit einer rechtwinkelig abstehenden Gabel --13-- versehen. Die Wellengabel --13-- wird durch einen Exzenter --12-- in der Weise verstellt, dass der Hinterteil --11-- über den Umlaufweg des Windrades, in Windrichtung gesehen, im vorderen und hinteren Bereich im Sinne eines gleichgerichteten Drehantriebes auslenkt. Die durch den Zapfen --19-- der unteren Lagerscheibe-3-- führende Welle des Exzenters --12-- ist mit einem Hebel versehen und wird mittels einer Anstellfeder --17-- über einen Reglerring --16-- sowie den mit Fliehgewichten - versehenem Reglergestänge-14-- verstellt.

The invention relates to a vertical-axis wind turbine which can be aligned with the wind direction and which has flow profiles which can be pivoted about axes lying parallel to the wheel axis and which are arranged in a circle around the axis of the wind wheel, the flow profiles being adjustable in the most favorable angle of attack with respect to the wind direction with respect to the wind direction are. In this known design, the wind turbine has swiveling, one-piece and thus rigid flow profiles which, particularly when they are inclined to the wind direction, produce air vortices which cause the wind turbine to lose power.
This disadvantage is avoided according to the invention in that the flow profiles consist of two parts lying one behind the other in the direction of flow, the front parts of which are always aligned parallel to the wind direction and the rear parts of which, viewed in the wind direction, via the circulation path of the wind turbine, in the front and rear area in the sense of a rectified direction Rotary drive can be deflected by the eccentric drive.
In the drawings, an embodiment of the invention is shown. FIG. 1 shows a vertical section through the wind power machine along the line II in FIG. 2. FIG. 2 shows the top view of the wind power machine in an embodiment with four flow profiles in the rest position. In FIG. 3 a wind power machine with eight flow profiles is in the working position shown, whereby essentially only the adjustment by eccentric and eccentric fork is emphasized.
Fig. 4 shows the flow profile positions over the circulation path of the wind turbine, the front parts of the flow profiles consisting of two parts lying one behind the other in the flow direction are always aligned parallel to the wind direction and their rear parts over the circulation path of the wind turbine, seen in the wind direction in the front and rear area in In the sense of a rectified rotary drive can be deflected by the eccentric drive.
An upper --2-- and a lower --3-- bearing disc are permanently connected to the central axis-l-fixed. In the upper bearing disc --2-- there are flow profile shaft bearings -18- and in the lower bearing disc --3-- journal --19--. In the inner upper end of the central axis - a control shaft --5-- is supported by ball bearings --20--. The control shaft --5-- which runs into a crank pin is used to support the control disc --4-- and is equipped with a wind
EMI1.1
assigned to a steering lever --7--. The steering lever --7-- is firmly connected to a profile shaft --8--. The profile shaft --8-- is supported by bearings --18-- in the upper bearing washer --2- and in the lower bearing washer --3-- on a journal --19--.
In order to enable the movement of a shaft fork --13--, the profile shaft --8-- is cranked --18- in front of the journal bearing. Each flow profile consists of a front part --9-- firmly connected to the profile shaft --8-- and a rear part --11-- mounted in the bearings --23-- by means of shaft --10--.
Each shaft --10-- is provided with a fork --13-- protruding at right angles at the lower end. The shaft fork --13-- is adjusted by an eccentric --12-- in such a way that the rear section --11-- deflects in the windward and forward direction in the front and rear area in the sense of a rectified rotary drive . The shaft of the eccentric --12-- passing through the pin --19-- of the lower bearing washer-3-- is provided with a lever and is activated by means of a spring clip --17-- via a regulator ring --16-- and the with centrifugal weights - provided control linkage-14-- adjusted.
